Among the elements of the main group, the general trend in the first ionization energy moving across a period is not followed between group 2 and group 13. WebSep 14, 2024 · Periodic trends are specific patterns that are present in the periodic table that illustrate different aspects of a certain element, including its size and its electronic properties. Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character.
